Arterial blood gases: The value obtained from arterial blood gases or ABGs (SaO2) describes the oxygen saturation of arterial blood. It is obtained by drawing blood from an artery such as the radial artery in the wrist or the femoral artery in the groin. ABGs are measured in millimeters of mercury (mmHg) and can be a clue as to how efficiently your body is exchanging oxygen and carbon dioxide. In the absence of any of the above, a fluctuating oxygen saturation level between 92–97 shouldn't be a cause for alarm, so long as it doesn't fall below 88% (the W. O standard cut off). The event of a consistent SpO2 of below 90 is generally indicative of a chronic obstructive lung disease and you should seek medical help immediately. A blood oxygen level test measures the amount of oxygen and carbon dioxide in the blood. It also checks your blood's acid-base balance. Abnormal results can mean there's a. You will be near death before your blood oxygen goes below ninety. Our breathing is so efficient that the blood is 90–100% oxygenated even in severely suppressed wellbeing. Shortness of breath occurs not because there is insufficient oxygen in you.
How does COVID-19 lower a person’s oxygen levels?
Many people with COVID-19 have low levels of oxygen in their blood, even when they feel well. Low oxygen levels can be an early warning sign that medical care is needed.
What is a pulse oximeter?
A pulse oximeter measures how much oxygen is in someone’s blood. It is a small device that clips onto a finger, or another part of the body. They are used often in hospitals and clinics and can be bought to use at home.
Many people consider oxygen level an important sign of how well a body is working, just like a person’s blood pressure or body temperature. People who have a lung or heart condition may use a pulse oximeter at home to check how they are doing, as directed by their health care provider. People can buy pulse oximeters without a prescription at some pharmacies and stores.
Can a pulse oximeter tell if someone has COVID-19 or how well they are doing if they have it?
We do not recommend using a pulse oximeter as a way to tell if someone has COVID-19. Get tested if you have signs of COVID-19 or if you have been close to someone who has it.
If someone has COVID-19, a pulse oximeter may help them keep watch over their health and to know if they need medical care. However, while a pulse oximeter may help someone feel like they have some control over their health, it does not tell the whole story. Oxygen level measured by a pulse oximeter is not the only way to know how sick someone is. Some people may feel very sick and have good oxygen levels, and some may feel OK, but have poor oxygen levels.
Pulse oximetry results may not be as accurate for people with darker skin. Their oxygen levels are sometimes reported as higher than they really are. People who check their own oxygen levels, or those who check it for them, should keep this in mind when looking at results.
Oxygen levels may be low if someone feels short of breath, is breathing faster than usual, or feels too sick to do their usual daily activities, even if a pulse oximeter says their oxygen levels are normal. Call a doctor or another health care provider right away if you have these symptoms.
What are normal readings?
A normal level of oxygen is usually 95% or higher. Some people with chronic lung disease or sleep apnea can have normal levels around 90%. The “SpO2” reading on a pulse oximeter shows the percentage of oxygen in someone’s blood.
If your home SpO2 reading is lower than 95%, call your health care provider.
For people with chronic obstructive pulmonary disease (COPD), emphysema, pulmonary fibrosis and other chronic lung diseases, keeping a close eye on their blood oxygen level is often part of the daily routine. However, for people living with COPD and other chronic lung conditions, receiving enough oxygen can be challenging. Every cell, organ and tissue in your body needs adequate oxygen, so oxygen is essential to a properly functioning body. When your body doesn’t receive enough oxygen, it’s unable to function properly. We’re here to help you better understand your blood oxygen level, how your body gets oxygen and what it could mean for you.
Oxygen and the Body
Your body uses oxygen in various ways to keep you at your best. Your blood transports oxygen throughout your body. Your body contains many different types of blood vessels, which act as the road system for your blood to travel throughout your body. Oxygen-rich blood travels through arteries and arterial branches to deliver oxygen and essential nutrients to your body. Capillaries are small, thin blood vessels that connect arteries and veins. Capillaries are important because they allow oxygen, nutrients, carbon dioxide and waste to pass to and from the tissue’s cells. Oxygen-poor blood travels through veins back to the heart and lungs where it will be re-oxygenated.
Your heart and lungs work together to deliver oxygen to your body, and your lungs inhale oxygen-rich air and exhale carbon dioxide. The heart pumps your blood to your lungs, so your blood can become oxygenated. Then, your heart pumps the oxygenated blood through your arteries and sends your blood to deliver oxygen to other cells, organs and tissues in your body.
How Your Heart and Lungs Deliver Oxygen Step-by-Step
Your heart has four chambers and four valves, which work to pump blood throughout your body. Your lungs and linked blood vessels deliver oxygen and remove carbon dioxide. The bronchi inside the lungs branch into smaller, thinner tubes called bronchioles. These tubes end in bunches of tiny, round air sacs called alveoli. Alveoli are covered in capillaries, and these capillaries connect to a network of veins and arteries.
The pulmonary artery and its branches deliver oxygen-poor blood to the capillaries that surround the air sacs. Once inside the air sacs, carbon dioxide moves from the blood and into the air to be exhaled while oxygen moves from inhaled air into the capillaries. Oxygen-rich blood then travels to the heart through the pulmonary vein and its branches, and on to the rest of the body.
Here’s How Oxygen Is Moved Through the Heart and Lungs to the Body:
Normal Oxygen Levels For Elderly
A healthy, normal blood oxygen level remains around 95 percent to 100 percent. You can monitor your blood oxygen level at home with a pulse oximeter. Values below 90 percent are considered low.
When your body doesn’t receive enough oxygen and you have a low blood oxygen level, hypoxemia or hypoxia, cyanosis and other conditions may occur. Because COPD and other chronic lung diseases restrict or obstruct normal breathing, low blood oxygen levels can be a serious issue. Hypoxemia or hypoxia occurs when your body has insufficient oxygen and can range from mild to severe. Symptoms of hypoxia can include severe shortness of breath, wheezing, constant coughing, a choking feeling and a bluish discoloration of the skin (cyanosis).
Chronic hypoxia can lead to cerebral hypoxia or brain hypoxia, which means that your brain cells could become seriously damaged within minutes.
If you suspect hypoxia call your doctor immediately. For cerebral hypoxia, call 911.

Normal Blood Oxygen Level By Age
Many doctors will prescribe oxygen therapy to help you receive enough oxygen and to improve your blood oxygen levels. Your doctor may also prescribe breathing exercises, diet and exercise changes, pulmonary rehabilitation and medications to help you breathe. Keeping a close eye on your blood oxygen level is important as well. Remember to see your doctor regularly even if you’re feeling well, so you and your doctor can work together.

In combination with traditional treatments, many people with COPD and other chronic lung diseases have seen improvements to their pulmonary function after cellular therapy. A relatively new treatment, cellular therapy works to promote healing from within the lungs, potentially improving lung function. In fact, many patients report coming off or significantly reducing their oxygen therapy use after treatment.
